1.5 seconds? The clock is two seconds fast this morning due to its natural rate and the leap second. By the way, did anyone catch the seven pips live on BBC Radio 4 last night? Using the BBC's "listen again" feature, none of the other BBC radio stations carried the pips at midnight; they all (or mostly all) used Big Ben. And the listen again feature for Radio 4 just before midnight is a repeat of an earlier program when they announce the time as 5 p.m.!

Here is an easy question to start off the New Year... Every Sunday at 08:00 I check the first stroke of the hour-bell of the University Clock against a radio-controlled UTC clock. If it is slow I add coins to the tray on the pendulum. If it is fast I remove coins. My formula for the required adjustment includes a figure for: Last Week's Gain [LWG] Here are my recent observations: 25 December clock 0.5 seconds fast 1 January clock 2.0 seconds fast Is the appropriate figure for LWG: a) 0.5 seconds b) 1.5 seconds c) 2.5 seconds Frank Frank H.
